Microplastic Identification of Tinfoil Barb (Puntius schawanafeldii) in Koto Panjang Dam Kampar Regency Riau Province
AI summary Read the abstract
This Indonesian study identified microplastic particles in the digestive tracts of tinfoil barb fish (Puntius schawanafeldii) from Koto Panjang Dam in Riau Province. It confirmed that microplastics from degraded plastic waste in the reservoir were ingested by this omnivorous fish species.
Plastic waste can be found everywhere, including in the Koto Panjang Dam. As the plastic waste degraded, the microplastic materials may be distributed in the water and it may be accidentally swallowed by omnivorous fishes such as Puntius schawanafeldii. To understand the presence of the microplastic materials in the fish stomach, a research has been conducted in December 2020 - February 2021. The number of P. schawanafeldii captured was 30 using fish net in 3-5 inch mesh size. The fish was dissected and the stomach was removed. Then the stomach content was added with 10% KOH andwas incubated for 2 weeks to delute the organic materials. Then was investigated under a binocular microscope to find out the microplastic materials. Results shown the type of microplastic present in the stomach of P. schawanafeldiiwas namely film, fibre, and fragment. The most common type of microplastic found was film, followed by fragments and fibre. The abundance of microplastic in the stomach of P. schwanafeldii was around 2 – 15,8 particles/fish

Identifikasi Cemaran Mikroplastik pada Ikan Nila (Oreochromis niloticus) dan Ikan Puyau (Osteochilus vittatus) di Perairan Waduk Benanga, Samarinda
AI summary Read the abstract
Researchers examined tilapia and puyau fish from the Benanga Reservoir in Samarinda, Indonesia, and found microplastic contamination in all 12 fish samples. A total of 155 microplastic particles were detected across the gills and digestive tracts, with fiber-type particles dominating in both species. The study highlights that plastic waste mismanagement around the reservoir is leading to microplastic accumulation in locally consumed fish.
